I have recently started practicing with penetration routines. Mostly coin in bottle. I have done factory sealed, bullet, and coin in soda can. All three tricks work very nicely for me and I am still practicing to make them all better. They are all great tricks to learn and all consist of very little or no sleight-of-hand. I am still looking for more tricks that consist of penetrating solid through solid and once I find some I will be sure to upload them on youtube and get some feedback. There is so much I am wanting to do, different ideas keep running through my mind. Well, I gotta get back to work. Mystifire!!!
